Abstract
To find out the response of potted gerbera under different light spectrum wavelengths of solar radiation was carried out. Three gerbera cultivars viz. V1 (red), V2 (pink), V3 (brick red) and seven treatments viz. L1 (full spectrum), L2 (no spectrum), L3 (cut of 380 - 750 nm wavelength), L4 (cut of 620 - 750 nm wavelength), L5 (cut of 450 - 495 nm wavelength), L6 (cut of 495 - 570 nm wavelength) and L7 (cut of 570 - 590 nm wavelength) were exerted on the experiment. Among the cultivars brick red was the best one. Plants were green because they reflected 495 - 570 nm wavelengths (green band) from the visible spectrum of solar radiation. Current findings indicated that of 495 - 570 nm wavelengths (green band), the plants responded alike to the full spectrum. No spectrum provided the worst result in all attributes of gerbera. Number of flower, peduncle length, peduncle diameter, flower head diameter and bending percentage were least after no spectrum in all the treatments. All the treatments except full spectrum and of 495 - 570 nm wavelength (green band) restricted for the entrance of the 620 - 750 nm wavelength (red band); 620 - 750 nm wavelength (red band) of light was very important for the plants. Besides, absence of 620 - 750 nm wavelengths (red band) and 450 - 495 nm wavelength (blue band) drastically hampered plant growth, yield and quality contributing characters.
